Windows’ Explorer detail bar also lists this info when you select a video, however it doesn’t work on all videos. To check the video and audio codecs in any video, you can use MediaInfo.Audio: AAC, MP3, AC-3, Apple Lossless, ALS, SLS, Vorbis.(Of course, for this guide and site, we suggest you use a good intermediary codec like Huffyuv, and are converting your videotapes to DVD or Blu-ray. If its a compressed format like H.264 which includes MP4 and MKV containers then Avidemux may first index the file. Video: H.264/MPEG-4 AVC, H.265/HEVC, H.263, MPEG-2 Part 2, MPEG-4 ASP, VC-1, Dirac and others Avidemux should be able to open most common formats without an issue.For instance, to use the MP4 Muxer, you’ll need video with one of the following codecs:.If you need a specific container, you can take a look at this Wikipedia comparison table for a list of the compatible video & audio codecs for every possible container out there (MP4, FLV, WebM etc.).

If all the videos have the same container, you can select the original container for output if it’s supported by Avidemux.Avidemux not only supports MP4 but it also is capable of embedding subtitles so perhaps you can save yourself loads of video-converting steps (though you might still benefit from using dedicated converters for iPhone, PSP, etc.Quick Guide to Selecting a Suitable Codec and Container Pair Nowadays, if you own any sort of portable device, be it an Android smartphone, an MP3 player (iPod Touch) or some gaming device like the PSP, you will certainly need your videos to be in MP4 format. A limitation that you're presented with if you use VirtualDub a lot (despite all it can do) is that this Windows-only program only accepts a small set of video file types, mainly AVI, MPG, and MPEG. One of these features I previously discussed is the ability to embed subtitles permanently in videos. Although Avidemux isn't a powerhouse video-editing software, it actually has a lot of the features that I thought made VirtualDub shine for the price of $0. It is one of many video editors for Linux, some of which are meant for more professional video production ( Cinelerra and Lightworks).
